Mosquito beater granules are a type of pest control product specifically designed to eliminate mosquito larvae and prevent their development into adults. These granules typically contain active ingredients that target mosquito larvae, such as Bacillus thuringiensis israelensis (Bti), which is a bacteria that kills mosquito larvae by ingesting them. The granules are applied to areas where mosquitoes are likely to breed, such as standing water or damp soil, and effectively control mosquito populations, reducing the risk of mosquito-borne diseases.
